I feel like the only thing HDMI has going for itself is ARC.

DisplayPort is superior in every other way imaginable. Except for the fact that almost no TV supports it.

Low-end monitors also don't usually have them, but as far as computer monitors go, I'm not interested in the low-end ones.

As for TVs - just give me a dumb screen with ports. I'm going to attach Apple TV to it anyway.



HDMI is ruling because of momentum and ubiquity in the tv room.

No device output in DP, no device accepts it, so no pressure on device to accept/output it. I guess the license price is low enough.

On computers, it sort of evolved where DVI was, you get mort port, you get better feature set, it's just superior.

But in the non-tech market I think the "real" fight will end up being hdmi vs usb-c, both of them are evolving to the point where they feed everything ethernet included. HDMI has ARC and waayyyy simpler cable and port compatibility (one version to check), usb-c has power output and every single pocket device and laptop/tablet/...

HDMI ethernet and HDMI eArc use the same pins. eArc won, HDMI ethernet is pretty much dead.

Yeah, if we exclude basically every half decent GPU and ~70% of laptop USB-C ports in existence.


I was talking about the TV room device, as opposed to the computer devices.


I use an HDMI to HDMI cable to connect my MBP to my 38" monitor (3840 x 1600, @ 85Hz). Would I get any benefit from using a USB-C to DP cable instead (e.g. running at the monitors maximum refresh rate)?


Unanswerable without specifying what laptop you have.


Sorry, I should have Googled before asking the question. I just did, and see that my monitor (Dell AW3821DW) supports only 85Hz over HDMI, but up to 144Hz over DisplayPort.

The laptop's spec page doesn't say what refresh rates are supported for external displays (except saying at least 60Hz): https://support.apple.com/en-us/111901

I'll buy a new cable right now :)


Yes that macbook pro supports outputting even 4K @ 144hz over displayport so it should work easily.


With the new cable, MacOS is showing the refresh rate is variable 1Hz to 144Hz.


Those generally aren't in the living room

So frustrating. I'm using a 42" LG OLED TV as a monitor right now. Very nice monitor at half the price of the same panel in a "real" monitor. I'm driving it with an AMD card at 60 Hz for exceedingly stupid reasons.


FWIW after reading though lots and lots of posts in the original bug report thread for this issue, I bought a Cable Matters “8K DisplayPort 1.4 to HDMI 2.1 Adapter” and it works perfectly to drive my Sony TV at 4K/120 from an AMD 6900XT on Ubuntu 24.04.


So true, I picked up the Samsung G80SD "Smart Monitor" and the deciding factor was literally just that it supports eARC, allowing me to use my Sonos Beam soundbar with my computer and supporting compressed audio formats like Dolby Atmos.

To make things even worse, this monitor supports sending back the ARC audio over DisplayPort, but only in stereo. If I use HDMI between the monitor and the computer, I get all of audio channels.
